This 30mm Tie On Block High Load Sheave with Soft Shackle from Allen boasts a stainless-steel head loop that adds significant strength and reliability to our Tii-On range. This loop also ensures proper orientation during use, while the central axle and correct attachment method are crucial for optimal strength. With the option of a soft shackle, the large central rivet not only reduces weight but also offers a rope-friendly attachment, making it ideal for use in a cascade system. Our patented bearing system, which utilizes twin rows of stainless-steel ball bearings on a stainless-steel rail, sets us apart from other bearing systems and provides superior load-carrying ability and longevity.
